Appeal No. 1998-0750
Application 08/232,135
We agree with the examiner. Under the example espoused by
the examiner, when a 0 voltage is applied as a second voltage
signal in response to a comparison in differential amplifier 1,
the preceding second voltage is removed and the pixel will turn
off in accordance with the claim. The pixel cannot remain on with
0 voltage applied across it. Furthermore, the examiner’s
statement to the effect that a 0 level voltage is applied to a
pixel is just another way of saying that no voltage is applied to
the element.
Whereas appellants have not specifically argued dependent
claims 11 and 13, or independent claim 28 and claim 29 which
depends therefrom, we will sustain the rejection of these claims
as obvious over Fukuoka. Because appellants argue that claims 17
and 32 are allowable for the same reason as claim 7, and we will
sustain the rejection of claim 7 as indicated above, we will
sustain the rejection of claims 17 and 32 as obvious over Fukuoka.
As to independent claim 47, it is argued that Fukuoka does
not teach or suggest providing the sampled current to an external
circuit. We disagree. The sampled current in the reference is
carried over a feedback line to an input of differential amplifier
1 The terminology “external circuit” is broad and differential
